PIS audio and video optical transceiver is a multi signal fusion fiber optic transmission device tailored by Orivision Electronics for the passenger information system (PIS) of rail transit. The device integrates 1 HDMI audio and video channel, 2 RS232 control signals, and 2 stereo audio channels for transmission through a single fiber optic cable, fundamentally solving the tedious problem of multiple cable layouts in traditional solutions and achieving the minimalist deployment concept of "one fiber carrying all signals".
In terms of image quality performance, it supports 1080P@60Hz to 4K@30Hz Resolution, 10 bit color depth ensures delicate and full colors on the screen, without delay or tearing. The HDMI 1.3/1.4 protocol is adaptive and perfectly compatible with various mainstream commercial screens. Single fiber single-mode optical fiber transmission can reach up to 10KM, with stable optical power (-5dBm transmission/-18dBm reception). The natural electromagnetic interference resistance of optical fiber ensures long-distance lossless transmission of signals, especially suitable for strong electromagnetic environments along rail transit lines.
In terms of deployment flexibility, the sending end supports modular configuration of 1/4/8/16 channels, which can be flexibly selected according to different scales of PIS systems such as subway stations and high-speed railway stations. The receiving end has dual screen driving capability, and one receiving end can simultaneously drive two back-to-back installed display screens (such as the front and back of the platform), greatly reducing equipment procurement and installation costs. RS232 baud rate 4800-112200 intelligent matching, 3.5mm stereo audio interface, full interface design ensures seamless compatibility with various PIS devices. Plug and play, no software configuration required.
